You're confusing yourself. I never said it was shut down by "militia groups". The Police Superintendant shut it down over what the police said were credible threats from militia groups. Oregon state police have the authority to do what the Governor asked them to do.
I'm no expert, no, but I'm pretty sure its fairly uncommon for state capitals to get shut down by credible threats from American militias.
I don't know why they aren't being treated like terrorists because thats what they are. You can wrap yourself in the American flag but it does not make you any different from any other group that uses threats of violence and fear to go against the majority to get their way.
And this happened because the majority want a cleaner future on this planet? Thats the truly batshit crazy part of all of this.
